. >> jon krakauer is also a best-selling author and mountaineer who wrote into thin air and into the wild. he was one of mortenson's earliest backers, donating $75,000 to his nonprofit organization, but after a few years, krakauer says he withdrew his support over concerns that the charity was being mismanaged, and he later learned that the korphe tale that launched mortenson into prominence was simply not true. >> did he stumble into this village in a weakened state? >> absolutely not. >> so nobody helped him out and nursed him back to health? >> absolutely not. i have spoken to one of his companions, a close friend, who hiked out from k2 with him. this companion said greg never heard of korphe till a year later. >> strangely enough, krakauer's version of events is backed up by greg mortensen himself in his earliest telling of the story. in an article he wrote for the newsletter of the american himalayan foundation after his descent from k2, mortenson makes no mention of his experience in korphe, although he did write that he hoped to build a school in another village called khane.
